So we are given the equation :
[tex]y=3-4x[/tex]
In order to get the y-intercept, simply use the value x=0 in the equation like this:
[tex]y=3-4\times0=3[/tex]
The y intercept is [tex]y=3[/tex]

We can rewrite the equation given above as,
   y = 3 - 4x

This item asks us to determine the value of the y-intercept. The value is calculated by letting x of the equation be equal to zero. Applying this methodology to the given above,

  y = 3 - 4(0)
   y = 3

Hence, the y-intercept of the given function is 3.
